Answer:

  4. 11/6, 121/36

  5. 5/8, 25/64

  6. 4/7, 16/49

  7. 14/9, 196/81

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding legs:

  perimeter ratio = red leg/blue leg

The area ratio is the square of that:

  area ratio = (perimeter ratio)²

__

<h3>4.</h3>

perimeter ratio = 11/6

area ratio = (11/6)² = 121/36

__

<h3>5.</h3>

perimeter ratio = 5/8

area ratio = (5/8)² = 25/64

__

<h3>6.</h3>

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

__

<h3>7.</h3>

perimeter ratio = 14/9

area ratio = (14/9)² = 196/81
